DISPLAY APPARATUS.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed February 8, 1911. Serial No. 607,419.

To all whom it may concern:

Be it known that I, KIHEI Kolnn, a citizen of Japan, and a resident ofthe city of Seattle, in the county of King and State of lVashington,have invented certain new and useful Improvements in Display Apparatus,of which the following is a specification.

My invention relates to apparatus of the above type and has for aprimary object the provision of a construction wherein a plurality ofadjustable sections forming a dislay face are controlled by mechanismfor movement in a successive manner to the position of display, andsubsequently removed as a unit.

A further object consists in the provision of novel mechanism foralternately moving a plurality of aprons for projection of one beyondthe other.

Other objects will be set forth as my description progresses and thosefeatures of construction, arrangements and combinations of parts onwhich I desire protection, succinctly defined in my annexed claims.

Referring to the accompanying drawings wherein like numerals ofreference indicate like parts throughout: Figure 1 is a longitudinalsection of an apparatus, constructed in accordance with my invention, astaken on line 1-1 of Fig. 2, parts being broken away. Fig. 2 is ahorizontal section taken through the upper portion of the casing. Fig. 3is a section taken on line 3-3 of Fig. 1.. Fig. l is a fragmentarysection, illustrating more particularly one of the adjustable drivingconnections and its shifting device, and Figs. 5 and 6 are sectionalviews illustrating more particularly the releasable connections providedfor the gears on the apron rollers.

I have herein illustrated my invention combined with a duplicate displaydevice comprising a casing 1, the said casing being provided in itsopposite side walls with display openings 2, 2, with each of which isassociated a respective display face conveniently consisting of a pairof aprons 3, 3 the displaying portions of the latter or inner apronsnormally projecting below the former and thereby combined as extensionsthereof, as clearly shown in Figs. 1 and 3. Each pair of aprons isoperated to be successively advanced and simultaneously retracted bynovel mechanisms which being identical in construction, a description ofone will suffice.

Aprons 3, 3 are secured at their upper end portions to respectiverollers a, at, one of which is spaced forwardly of the other andprovided wit-h gears 5, 5 and 6, 6 respectively, the first named pair ofsaid gears being loosely mounted on respective end portions of roller4:. Gears 6, 6 are of greater width than gears 5, 5, and rollers 4- ofgreater diameter than rollers l, to thereby obtain the increased travelof apron 3 with respect to apron 3. In this connection however, it willbe observed that the increasing of the diameter of rollers 4 can beavoided by merely adding to the width of gears 6, 6. Gears 6, 6 areloosely mounted on the end portions of roller 4 with the former thereofin alinement with gear 5, to be simultaneously engaged by a pinion 7,forming an ad justable driving connection therebetween, and the latterarranged at the inner side of gear 5 in the path of a pinion 7 whichlatter upon being shifted axially, as hereinafter set forth, engagessaid gears 5, 6 to transmit motion thereto alternately. Pinions 7, 7 aresplined on respective end portions of a screw shaft 8, feathers on thebores of said pinions engaging in respective longitudinal grooves of theshaft, (see Fig. 4), whereby said pinions are held for simultaneousrotary movement with the shaft while being free for lengthwise movementthereon.

Reference numeral 9 indicates shifters rotatably receiving pinions 7 7,and having threaded engagement with shafts 8. Gears 5, 6, 5 and 6 havereleasable connection with their respective rollers, such connectionbeing conveniently effected through the medium of pawl and ratchetdevices 10, the ratchet wheels of which are fixed to the roll ers whilethe pawls are carried by the loose gears, (see Figs. 5 and 6), and thesepawl and ratchet devices are set so that those of gears 5, 6 drive inthe reverse direction to those of gears 5 and 6. Thus pinion 7 whenmoving inwardly on shaft 8 will successively engage gears 5, 6 tothereby alternately advance or lower aprons 3, 3. During this movementpinion 7 in meshing with its gears 5 and 6 fails to have its rotarymovement transmitted to the rollers 4, 4:, said gears 5 and 6, throughtheir pawl ratchet devices 10, at such time turning idly. Reversal ofthe direction of rotation of shaft 8 causes pinion 7 to simultaneouslyengage gears 5 and 6 and thereby move aprons 3, 3 as a unit from thefield of display.

Reference numeral 11 indicates a reversable motor mounted on a suitablesupport 12 and connected by belts 13 to shafts 8 for transmitting powerthereto.

Inasmuch as shafts 8 are simultaneously rotated, I prefer to connect theshifters 9 of one shaft with those of the other and this is effected bysuitably fixing the adjacent shifters to an intermediate rigid connector9 Reference numeral 14 indicates weights which are provided on the freelower end portions of aprons 3, 3, said weights consisting of barshaving extended end portions engaged in guide ways 15 of casing 1.

For reversing the direction of rotation of motor 11, I have shown areversing switch 16, of a well known type, the same consisting of a pairof pivoted arms connected by a bar 17 of insulating material, the saidarms when switched moving alternately into. engagement with contacts ofrespective leads 18, 18 of the motor, as shown.

For controlling switch 16, I have pro vided strike parts 19 and 20,thesecomprising angularextensions of switch bar 17 and each lying in the pathof the projecting end portion of the weight bar 14 of a respective apronof one pair, the strike part 20 projecting into the path of apron 2)adjacent the lower end portion thereof while strike part 19 projectsinto the upper portion of the path of apron 3.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent of the United States of America, 1s:

1. In display apparatus, a display face composed of a plurality ofsections, means supporting said sections for projection one beyond theother, and means for automatically advancing said sections successivelywith an increased travel of one over the other and retracting the samesimultaneously.

2. In display apparatus, a display face composed of a plurality ofaprons normally projecting one beyond the other, rollers to Copies ofthis natent may be obtained for five cents each, by addressing theWashington, D. 0.

which said aprons are secured, and operating means for said rollerscontrolled for rotating the same successively in one direction andsimultaneously in the reverse direction.

3. In display apparatus, a pair ofrollers, aprons secured to saidrollers for projection of one beyond the other, a pair of rotatabledrivers supported for rotary and axial movements, and cooperating drivenmembers on said rollers arranged in the path of said drivers toalternately connect said drivers with said rollers.

4. In display apparatus, a pair of rollers, a pair of gears on eachroller releasably connected therewith, each gear of a roller beingconnected for transmitting movement to its roller in a respectivedirection and free for independent movement in the reverse direc tion, ascrew shaft, drive pinions splined to said shaft and each mounted formovement thereon into and out of mesh with adjacent gears of saidrollers, means for rotating said shaft, means for shifting said pinionsaxially on said shaft, and means for reversing the direction of rotationof said shaft.

5. In display apparatus, a pair of rollers, a pair of gears on eachroller having a pawl and ratchet connection therewith, the connection ofone gear of a roller being relatively reverse to that of the other gear,whereby each gear of a roller has connection therewith for driving thesame in a respective direction, one gear of a roller being arrangedopposite to one of the gears of the other roller, whereby they canreceive power simultaneously, the other gears of said rollers beingoflset relatively to one another, a screw shaft, means for rotating saidshaft, a pair of pinions splined to said shaft, shifters having threadedengagement with said shaft for moving said pinions thereonsimultaneously in a longitudinal direction, each of said pinions beingarranged for movement into driving connection with respective adjacentgears of said rollers, and

means for reversing the direction of rota-- tion of said shaft.
